For valves that will and do last decades, buy Bermad. I have ones that have been in continuous daily (not winter) since the 90s. They are the best. Valves and filters, and pressure regulators look for Bermad, manifolds Tavlit and emmiters/drippers Australian or Israeli commercial brands.
Israel and Australia make the best stuff because they are basically desert environments. Can be very much cheaper than “home” irrigation brands too, like 70%+ cheaper if you buy them buy the bag. Plenty of spares too for less than “home” gear.
